Red wine has been long established to have health benefits, many of which can be attributed to a chemical called resveratrol that is found in the grapes used to make the wine. Now, new research from the Henry Ford Hospital in Detroit has found that red wine and red grapes may also help protect against hearing loss. In animal experiments, the long-term effects of noise-related hearing loss could be lessened if resveratrol was consumed before listening to extended periods of loud noise.

The proverbial "midnight snack" may be a staple of your diet, but it also could be contributing significantly to your waistline. Research at Vanderbilt University found that the body tends to convert late-night eats into fat instead of into fuel, which it does during the day. The study also concluded that disrupting the circadian clock, which signals sleep and wakefulness to the body, can affect metabolism and lead to weight gains. Shift workers have been found to be at a higher risk of developing diabetes than people who follow a standard 9 to 5 schedule.

Okay, so who knew sweat had medicinal value? Research published in the Proceedings of the National Academy of Sciences reports that a protein found on human skin and activated during sweating could help fight disease. The protein – Dermcidin – is being used to create an antibiotic that could be effective in fighting hospital superbugs and deadly strains of tuberculosis.

Before ordering off of a menu at a seafood restaurant, keep in mind that you may not be choosing what you think you are. . A new report from Oceana, an ocean conservation organization, found that nearly one-third of all U.S. fish may be mislabeled, often resulting in you getting a cheaper type of fish than you think you're ordering. In sushi restaurants, as much as 74 percent of the fish could be mislabeled, according to the report. The U.S. imports roughly 90 percent of the fish sold for consumption, while less than 1 percent gets inspected. The study warned that fraud has become a serious issue.

We know, we know – nobody wants to see their grandparents on Facebook. But a new study from the University of Arizona found that use of the social networking site could help boost cognitive function in people over the age of 65. Following training sessions for Facebook and encouragement to use the website regularly, seniors in the study performed 25 percent better in "mental updating," an aspect of cognitive function.

Two Cambridge University professors, James Watson and Francis Crick, were among the many scientists competing to unlock the secret of DNA, the molecule containing the human genetic code. And on this February morning they make what’s now considered one of the seminal discoveries of the 20th century—they figure out DNA’s double helix structure that allows it to “unzip” to create copies of itself and make it possible to pass genetic instructions from one generation to another.

At lunch that day at a nearby pub called The Eagle, Crick announces to the other professors gathered there that “we have found the secret of life.” Two months later, they would publish in the journal Nature a one-page report with the understated title "A Structure for Deoxyribose Nucleic Acid." It’s accompanied by a schematic drawing of the double helix by Crick’s wife, Odile.
